GEORGE FAULKNER, OF INDIANAPOLIS, INDIANA.

GAS PRESSURE-REGULATOR AND CUT-OFF.

SPECIFICATION forming part of Letters Patent N o. 384,967, dated June 26, 1888.

Application filed December 27, 1887. Serial No. 258,994.

To a/ZZ 1071/0111, it may concern:

Be it known that I, GEORGE S. FAULKNER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana,I have invented a new and useful Improvement in Gas Pressure-Regulators and gut-Offs, of which the following is a specificaion.

My invention relates to an improvement in that class of gas pressure regulators and cut-offs in which the flow of gas from the mains to a consumers system of supply-pipes is so controlled that a uniform pressure' will be maintained in the consumers pipes under ordlnary conditions of use,andin which communication Withthe main is automatically entirely shut olf when from any cause the pressure, either in the consumers supplyvpipes or in t-he mains, falls below apreviouslydetermined amount.

The object of my improvement is to provide a new arrangement of parts in a regulator of the class above mentioned, whereby the device occupies but a smallV space, and is adapted to be attached to a vertical line of pipe Without disturbing the continuous alignment of the pipe, all as hereinafter fully described.

The accompanying drawing represents my invention.

The figure represents a sectional view taken vertically through the center of the device.

A represents a substantially rectangular case divided interiorly into the chambers B and C by the partition d. Chamber B communicates with chamber C through an opening, e, which is closed by the valvef. On the lower side of chamber B, in the partition d, is an opening, g, which is closed by the valve h, and to which the inlet-pipe I, leading to the main, is connected. Valvesfand h are of equal area, and are connected to the opposite ends of a lever, J, and ,on opposite sides thereof at equal distances from the fulcrum 7c, which is secured to the side of the chamber B, the purpose being to cause the pressure against one valve to balance the pressure against the other, and to cause valve 7L to be closed by the movement of valvef beyond a certain point, as hereinafter explained. The outlet from chamber C is arranged di- (No model.)

rectly above the inlet to chamber B, so that the inlet and outlet pipes -I and X are in line vertically.

Secured to the top of case A, and communieating with chamber C, is a cup, L, having an annular groove, m, which is partly filled with a liquid, n, preferably mercury, into which dips the edge of an inverted sheetmetal cup, o. Valve f is connected with cup o by means of a rod, p. Erected on cup L is a standard, r, to which is pivoted the scalebeam lever s, having a graduated bar, t, on which is mounted so as to slide thereon a weight, u, having a set-screw, fu, by means of which the weight is adjustably secured to the bar. Lever s is connected to cup L by the link w. An opening closed by the plug y is formed in case A for the purpose of inserting u valvef. i

The operation of my device is as followsz.

in the mains increases to a point above that` required in the supply-pipes, cup o and Weight a are raised and valve f is momentarily closed, so that the pressure iu the supply-pipes is at once reduced to the point desired. If a break occurs, or any other accident occurs so that the pressure is materially reduced below the point desired, either in the consumers system of pipes or the main, the weight u opcrates through link w, cup o, rod p, valvef, and lever J, to close valveh, thus automatically cutting-offthe connection ofthe consumers system of pipes with the main. On a return of the pressure in the main and the inletpipe the whole force of the returning pressure is against valve h, and operates to keep said valve closed, `thus preventing the iooding with gas of the consumespremises. To reopen valve h and start the iiow of gas in the consum'ers system of pipes, it is necessary to raise lever s by hand.

I claim as my invention y In a gas pressure-regulator and cut-off,case A, having chamber B, provided with inletopening g, partition (l,havingopening e, and
